8. Conclusion

For industrial sectors where the occurrence of a failure leads to unacceptable consequences for those in charge of industrial installations, preventive maintenance represents a maintenance strategy that will minimize the probability of a fortuitous shutdown. Numerous techniques and technologies have been developed to detect and monitor potential failures. However, preventive maintenance should be reserved for critical equipment, given the associated costs and the high level of qualification required of personnel. To select the technical tasks, their frequency and their implementation strategy, it is advisable to obtain the opinions of manufacturers and experts. At present, the development of the Industry 4.0 concept and the methods of prognosis and estimation of operating time before residual failure within the framework of PHM (Prognostics and Health Management) and RUL (Remaining Useful...
